Bonjour,
je ne connais pas grand chose au fonctionnement des disques durs mais je possède un disque dur externe avec des vidéos personnelles et lorsque je le branche à mon PC maintenant Windows m'indique "voulez-vous formater le disque dur", ceci assez subitement car 10 minutes avant j'y avais accès. Impossible de voir les fichiers. Je ne voulais pas faire de bêtises et ne rien perdre, aussi j'ai lancé une analyse testdisk et je vous mets le log ici pour vous demander conseils avant de lancer une opération qui ne serait pas la bonne et qui engendrerait plus de dommages que de solutions.
Je vous remercie 1000 fois par avance pour vos conseils.

Re: disque dur subitement non reconnu par Windows
Essayez TestDisk, Advanced, Boot, RebuildBS, List.
Si vous voyez vos fichiers, Write, confirmer, Quit et redémarrer votre PC.

Re: disque dur subitement non reconnu par Windows
Bonjour M. Grenier, merci beaucoup pour votre réponse. Malheureusement pour moi ça n'a rien donné.
Après le RebuildBS le List ne m'a pas montré de fichiers.
Auriez-vous une autre idée de ce que je pourrais faire pour récupérer mes fichiers ?
Ci-dessous les captures d'écran et le log.
Encore merci.
